Application December 17, 1951, Serial No. 262,019

' 1 Claim.

The present invention relates to new and useful improvements in metal working tools for use primarily in conjunction with a dolly block in automobile body and fender work and has for its primary object to provide, in a manner as hereinafter set forth a device of this character comprising a novel construction and arrangement of pivoted, spring actuated hammer whereby dents, etc, may be expeditiously removed from metal.

Other objects of the invention are to provide a metal working tool of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a top plan view of a metal working tool constructed in accordance with the present invention;

Figure 2 is a view in side elevation of the tool, showing the device in use; and

Figure 3 is a view in transverse section through the head, taken substantially on the line 33 of Figure 1.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises an elongated handle 5 of appropriate shape. At its forward end portion, the side portions of the handle 5 are cut away or recessed, as at 6, in a manner to provide upper and lower stops 7 and 8, respectively.

A metallic arm 9 is mounted for swinging movement on the forward end portion Ii] of the handle 5. Toward this end, the arm 9 includes a bifurcated end portion II which straddles the handle portion If] and which is pivotally connected thereto, as at I2.

At its free end, the arm 9 terminates in a foot I3 having fixed thereon a longitudinally elongated striking head It in the form of a substantially rectangular metallic block. As best seen in Figure 3 of the drawing, the head I 4 includes a roughened or toothed striking face I5.

The arm 9 and the head I l constitute what may be considered a hammer which is designated generally by reference character I6. A coil spring I! is operatively connected t0 th 2 hammer I6. One end of the spring I i is connected at I8 to the handle 5 and the other end of said spring is connected at l9 to the hammer I6.

It is thought that the manner in which the device is used will be readily apparent from a consideration of the foregoing.

Briefly, a suitable dolly, as at 2. 3, is engaged beneath the work 2|. The other hand of the mechanic grips the handle 5 an the work is pounded with the hammer It. The construction and arrangement is such that a spring actuated slapper action is had which permits harder, faster pounding with a shorter, more accurate stroke which does not jar the hand of the operator. The toothed or roughened face I5 of the head I4 quickly restores the metal to its original shape Without stretching and with a smooth surface which substantially eliminates filing the work. The bifurcations II of the arm 9 are engageable with the stops 7 and 8 of the handle 5 for positively limiting swinging movement of the hammer It in both directions.

It is believed that the many advantages of a metal working tool constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

Having described the invention, what is claimed as new is:

A metal working tool comprising, an elongated handle, an arm comprising furcations on one end straddling an end portion of the handle and pivotally connected thereto, a serrated striking block of considerable area rigidly fixed on the free end of the arm, and upper and lower stops on the sides of the handle engageable with the furcations for positively limiting swinging movement of the arm in both directions, said lower stops extending forwardly beneath the pivotal connection for arresting and supporting said arm in a forwardly inclined position on said handle.
